NEWSPAPER PRINTING PRESS Filed Dec. 20, 1935 3 Sheets-Sheet 3 PatentedMar. 1, 1938 UNITED STATES PATENT OF E to Duplex Printing Press Company,Battle Creek, Mich, a corporation of Michigan Application December 20,1935, Serial No. 55,465

19 Claims.

This invention is an improvement in printing presses of the typeoriginally disclosed in Bechmans Patent No. 867,230 dated October 1,1907, and more particularly as disclosed in my companion application forNewpaper printing presses, filed June 4, 1934, Serial No. 729,013.

The invention disclosed in said application provides a multi-unit pressand folder, said'press having a plurality of interchangeable printingunits and a folder unit or units; which units can be arranged in anydesired relation in a line. Any desired number of units may be employedto produce a straight line, straight run, paper or papers of any desiredsize or number of pages.

Such invention provides a simple. and attractive press for newspaperpublishers who desire increased production and preferthe single pageplate economies and efficiencies and which press will conserve andretain all the advantages of the single so-called tubular presses inproduction and operation, with greatly increased net production speed;and in which any unit may be put into or out of operation as desired.

The object of the present invention is to provide means whereby twoplate cylinders are arranged in printing relation toa single blanketcylinder in such manner that if desired the paper may be printed inmulti-colors in a single passage through the press; and also to providemeans whereby the extra plate cylinders may be put out of operation ifit is desired to only print in one color.

Further objects of the invention are to provide novel means whereby theplate cylinders may be independently adjusted relatively to the relatedimpression cylinder, both for producing the impression pressure and alsoto enable the plate cylinder to be placed out of operative position ifit is not desired to use same.

The accompanying drawings illustrate a practical embodiment of myinvention, and I will describe the same in detail with reference to saiddrawings, and summarize in the claims the essentials of the inventionand novel combinations and construction of parts for which protection isdesired.

In said drawings:-

Fig. 1 is a side elevation of a printing press constructed in accordancewith my invention.

Fig. 2 is a vertical transverse section through such unit.

Fig. 3 is an enlarged detail view showing the construction of therespective plate cylinder supporting and. adjusting devices,

Fig. 4 is a side view of Fig. 3.

Fig. 5 is a side elevation similar to Fig. 1, showing one multi-colorprinting cylinder.

Fig. 6 is a vertical transverse section through Fig. 5.

Each printing unit comprises a perfecting printing mechanism with asingle or double color attachment, and as shown the perfecting unitconsists of cylinders I and la, and co-acting impression cylinders 2 and2a. The impression cylinders Z-and 2a are journaled at opposite ends inbearingspartly formed in the side frame members 3 and in blocks 30 whichare fastened to the members 3 by means of bolts 3d. The plate cylindersI and la are respectively journaled in annular heads do, on the lowerends of hangers 4, shown; more in detail in Figs. 3 and 4. The hangers 4are adjustably secured to the outer sides of the journal blocks 30 bymeans of bolts 40 which pass through slots 41)- in the hanger and aretapped into the blocks 3c. The hangers' 4 are vertically adjustable soas to regulate the impression pressure contact between the platecylinder and its related impression cylinder, by means of a supportingscrew 4d which is rotatably suspended in a lug 3e on the adjacent block3c, said screw having a threaded engagement with a socket in the upperend of the hanger 4 (see Figs. 3 and 4) The hanger 4 can be raised orlowered so as to adjust the plate cylinder l or Ia as desired relativeto its related impression cylinder by first loosening the bolts 40 andthen turning hanger bolt 4d. After the cylinder is adjusted it isfastened in adjusted position by tightening bolts 40.

In the construction shown in Figs. 1 and 2 a multi-color cylinder Mn islocated above each impression cylinder and is adapted to cooperatetherewith when it is desired to print in multicolor. The cylinder lm(see Figs. 3 and 4) is mounted in heads on the lower ends of hangers 5which are hung at their upper ends on pins 5a engaging eye-lugs 6a onvertically adjustable blocks 6. Each block 6 is hung on a rotatable bolt6b tappedinto the upper end of block 6 and hung on an eye 1a attached toan upper frame member "I mounted upon and secured to the top of member3. I

The members 5 and 6 when properly adjusted vertically may be rigidlyclamped in position by a through-bolt which passes through slots in themembers 5 and B and is tapped intothe frame member I. When it is desiredto adjust the cylinder im. the bolt 50 is loosened, then screw Bbxisadjusted to raise or lower cylinder lm to the desired position relativeto the periphery of the adjacent impression cylinder 2a; and whenproperly adjusted the bolt 50 is tightened and securely holds thecylinder in such adjusted position. When it is not desired to use eithercylinder Im, the bolt 50 can be loosened, and the hanger swung outwardthereby moving the plate cylinder away from the related impressioncylinder; and the hanger and cylinder may be held in such non-operativeposition by adjusting a bolt 56, tapped in the side of casting 5, untilits inner end engages a groove 5) in the bolt 50.

When bolts 50 are loosened their screw threads force them axiallyoutward allowing the hangers 5 to swing outwardly on the pins 5a. Theposition of the plate cylinder relative to pins 50a is such that ittends to swing outward by gravity when bolts 50 are loosened. Should theforce of gravity be insufficient to give the required clearance betweenthe two cylinders the inner ends of the screws 5e contact with the sidesof the grooves 51 in the bolts 50 and force the hangers 5 to swingoutwardly on the pins 5a, and also prevent the cylinder from swingingback to its former position until the bolts 50 are again tightened.Tightening the bolts 50 forces the hangers 5 against the blocks 6 whichare then held against the frames 1.

The cylinder lm is also adjustable vertically relatively to theimpression cylinder 2a by means of the screws 6b (Fig. 3) which are aduplicate of the screws 40/. by which the lower cylinder hangers 4d areadjusted.

Each plate cylinder i, l a is adapted to carry cylindric plates P,(Figs. 1 and 2) each of which will print one newspaper page of matter.The plates receive ink from suitable inking devices mounted below thecylinder in the side members of the unit frame.

Each plate cylinder lm may also be supplied with ink from an inkingmechanism mounted in the frame members 1 above such plate cylinder. Asthe inking mechanisms form no part of the present invention it isunnecessary to describe the same herein, and they are simplydiagrammatically illustrated in the drawings.

Ordinarily the ink for the lower plate cylinders I and la will be black;and the ink for the upper cylinders lm would be colored. In theconstruction shown in Figs. 1 and 2 a sheet could be perfected in blackand also in color.

In the construction shown in Figs. 5 and 6 only one multi-color cylinderlm is shown, and one set of inking mechanism mounted as above describedupon a frame member "Jr on top the frame 3. The frames l and law arepreferably made interchangeable, so that a frame 1x could be removed andreplaced by a frame I carrying two cylinders lm and their inkingmechanism, and thus enable the paper to be printed in more colors.

The web can be led through the press in various ways. As indicated inFigs. 1 and 2, the web can be led up over a guide roller 8 and thencebetween the cylinders l and 2, and. Im and 2, thence down between thecylinders 2, 2a; thence between the cylinders la and 2a and thecylinders 2a and Im, to a guide 8a, and thence up over a guide 8b to afolder (not shown). By

varying the lead of the web, or using different colored inks in thelower fountains, a large variety of multi-color effects can be produced.

If each printing unit of the press is two plates wide, it will printfour pages in multi-color. Six such units would produce 24 pages, theequivalent of a semi-cylindrical sextuple in straight run production.For a 32 page machine two more units would be employed.

Any number of such units may be employed, arranged in line, side by sidewith the cylinders parallel according to desired capacity of the press,as explained in my aforesaid application.
